Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a steel wire rope elastic elongation detection device. Background Art

[0002] Wire rope is a spiral bundle of steel wires twisted together according to certain rules with steel wires that meet the requirements of mechanical properties and geometric dimensions. Wire rope is composed of steel wire, rope core and grease. Wire rope is first twisted into strands by multiple steel wires, and then a certain number of strands are twisted into a spiral rope with the rope core as the center. In material handling machinery, it is used for lifting, traction, tensioning and carrying. Wire rope has high strength, light weight, stable operation, not easy to break suddenly, and reliable operation.

[0003] After searching, a utility model patent with the publication number CN114034278 A specifically discloses a detection device for the elastic elongation of a steel wire rope for an elevator, including a protective box body, a lifting assembly fixedly installed on the left and right sides of the protective box body, a lifting plate arranged at the upper part of the inner cavity of the protective box body, a mounting plate fixedly installed at the bottom of the inner cavity of the protective box body, a lower clamp fixedly installed on the upper outer surface of the mounting plate, a protective door arranged on the front outer surface of the protective box body, a tension sensor fixedly installed in the middle of the lower outer surface of the lifting plate, an upper clamp fixedly installed on the lower outer surface of the tension sensor, a mounting assembly fixedly installed on the right side of the lower outer surface of the lifting plate, and a distance meter fixedly installed on the lower outer surface of the mounting assembly. The detection device for the elastic elongation of a steel wire rope for an elevator described in the present invention has the advantages of being easy to stably control the lifting and lowering of the lifting plate, being easy to measure the elastic elongation of the steel wire rope, and being safe, and the distance meter being easy to install and disassemble.

[0004] However, when the detection device in the above patent clamps and fixes the wire rope, the staff needs to turn the bolts on the upper and lower clamps to loosen the clamps in the upper and lower clamps, then place the wire rope between the clamps, turn the bolts again, so that the clamps in the upper and lower clamps clamp the wire rope, and then start the device to detect the wire rope. However, this operation is relatively easy when detecting a single or a small number of wire ropes. When detecting a large number of wire ropes, this operation is time-consuming and labor-intensive, which is not conducive to the promotion and use of the detection device. Therefore, it is necessary for us to propose a wire rope elastic elongation detection device to solve the above problems. Utility Model Content
